T 0 (all whont it may concern.-

Be it known that I, ARTHUR M. EDWARDS, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Processes of Manufacturing Artificial Fuel, of which the following is a full, clear, and exact description.

This invention relates to an improved process of producing artificial fuel. Incidentally certain by-products of value are also produced.

My invent-ion consists in a process for man ufacturing artificial fuel consisting in mixing diatomaceous earth and crude petroleum and then heating said mixture so as to remove the vapors and illuminatingoil from the petroleum, and, finally, cooling the artificial'fuel produced, as will be more fully described hereinafter.

In the accompanying drawing the figure is a vertical section of the several forms of apparatus and mechanism employed in the hereindescribed process.

In carrying out my process I employ apparatus substantially like that illustrated in the drawing, comprising therein a suitable furnace u, across which is arranged at any desirable angle a converter b, which is preferably made of boiler-iron and is of a cylindrical shape. Said converter may be arranged in suitable bearing-plates c and c in the side walls a of the furnace. The converter is closed at its upper end by means of a plate 1), and arranged in suitable bearings within the converter is a shaft (I, provided with a suitable mechanism 0 for operating and revolving said shaft and its screw within the converter.

As will be seen from the accompanying drawing, the lower end 11' of the converter, projecting from the side of the furnace a, extends through the side of a Water tank or reservoir f, and the mechanism for operating and revolving said screw-shaft (I in this case consists of a miter-wheel d? on said shaft and a miter-wheel e on a shaft e adapted to be revolved in a standard f on the top of said tank or reservoir f.

The upper portion of the converter 1) is provided at the end projecting from the opposite side of said furnace at with a suitable hopper g, that is in turn provided with a shuttingoff device y. A pipe It extends from said end of the converter and leads into a tank or reservoir 1', said pipe being formed into a condensing-worm h and terminating at the bottom in an outlet-pipe k provided with a suit-able cock or faucet 1L3.

Although but one converter is illustrated in the accompanying drawing, it will be evident that I may use several, in-which case they are preferably placed side by side within the furnace in the manner just described.

To prepare the compound, I mix diatomaceous earth, clay, or ashes or other similar porous material with crude petroleum to form a paste. This paste is passed through the hopper g, and by operating the shaft d and its screw the conveQgr or drum 1) is partially filled. No particular proport-ionsof eartlnclay, ashes, or porous material and oil are used fur ther than .that whatever material is used is saturated with oil and then the mixture of oil and material is placedin the hopper and subjected to heat. The mechanism for operating the shaft and its screw is then stopped and the shutting-01f device in the hopper g is closed. The paste within the converter is subjected to the heat of the fire within the furnace aand by conversion the naphtha contained in the mixture passes off through the pipe h into the worm h as vapor, where it is condensed and is finally drawn off through the outlet-pi'pe 71 at the bottom of the tank l. As soon as all the naphtha vapors have escaped from the mixture within the converter the next vapors that are released are those used in common burning-oil, and these last vapors are collected in the same manner by being condensed in the still or worm h. After the naphtha and other vapors have been driven off the heavier illuminating-oil passes down through the lower end of the converter into the water, where it rises to the top. While the naphtha is passing off at one end the illuminating-oil is passing off from the other at the same time that artificial fuel is being formed. By my construction all of the volatile portions of the crude petroleum is driven off in a form ready for use at the same time that the fuel is being made. After the mixture within the converter has been sufliciently subjected to the heat and any naphtha vapor or other useful vapors contained in the mixture have escaped through the pipe h the residuum within the convertereylinder is turned into artificial fuel by the heat of the furnace, and so soon as the artificial fuel has thus been formed the shaft (1 and its screw d are again set in operation, whereby the artificial fuel is forced out of the open end (1 of the converter and dropped into the tank or reservoir f to be cooled.

There is no particular degree of heat required; but the material in the hopper is subjected to heat until all of the vapors have been driven 01f from the oil. Very little experience is necessary to estimate the length of time required. All of the coarser heavier parts of the crude oil are driven off, and the ARTHUR M. EDWARDS.
